Conformational changes in FPPS complex

Three crystal structures of human farnesyl pyrophosphate synthase (FPPS) in ternary complex with a novel bisphosphonate inhibitor reveal mechanistic insight of the conformational change in the C-terminal tail closure that is essential for catalysis.

Modeling macromolecules with nano-objects

Protein Nano-Object Integrator (ProNOI) is a novel software tool for generating atomic-style nano shapes in conjunction with biological macromolecules, allowing users to manipulate shape, dimension and position, and charge objects with user-specified charge density.

Structure of antigenic Toxoplasma proteins

The 3D structure of the 12 kDa excretory-secretory protein of Toxoplasma gondii reveals a thioredoxin-like backbone and three potential epitopes functioning as a single antibody binding site, aiding the development of an antigen detection test for toxoplasmosis.

Structural mismatch in homologous heme proteins

Structural mismatch between the only heme storage protein of Vibrio cholera, HutZ, and its homologous protein HugZ, suggests that deficiency in heme oxygenase activity might derive from a single residue shift.

Enhanced stability for Tyk2 protein kinase

The mouse Tyk2 protein kinase complexed to an ATP-competitive 3-aminoindazole inhibitor is stabilized relative to the unliganded enzyme, with the crystal structure revealing key differences in the glycine-rich loop conformation compared to those in human orthologs.
